Couch to 5K works! Here's proof...

Just because you don't run doesn't mean you can't. If you can walk for half an hour, chances are that you can pick up the pace and give running or jogging a try. 

BBC Get Inspired has teamed up with Public Health England's One You campaign to bring you the Couch to 5K Challenge, especially designed for people who have done little or no running.

Today Jon Barbuti is running the London Marathon for his autistic son Dylan, raising money for The National Autistic Society.

He said: "What autism needs isn't a cure, quacks claiming gluten causes it, or jabs or whatever; what it needs is simply greater awareness."

Two years ago Steven, 22, weighed just seven stone, was sleeping rough and a substance dependent, but then his life was turned around when he found The Running Charity, external, who work with young homeless people, helping them get back on their feet by giving a focus, a social group and achievable personal goals.

Steven wants to repay the group by raising money for them running his first marathon and is targeting a time of four hours (race number 56206).

"I found a place where I was supported, pushed and given the tools to address the problems I faced. It's been a long journey for me but I am now housed, a healthy 12 and a half stone, no longer using any drugs and I'm now a qualified personal trainer.

"I was given the chance to turn my life around through running and fitness and without the help of The Running Charity I would not be where I am now. It's a charity with ambitions to help as many people as possible and I can't wait to help them more."

Dame Kelly Holmes on BBC One who completed the race in 3:11 : "It was amazing, I think I was in a daze all the way around. 

"I could hear the crowd but I was switching off. At 19 miles I was thinking ‘this is it’ but I was still thinking 'just run!'"

The London Marathon couldn't be what it is without volunteers.

Here’s one gentleman running for Asthma UK dressed as Puff the Magic Dragon who has been caught by Ore on Tower Bridge.

“How is it going?” Ore asks.

Answer: “I was going alright until you stopped me.”

69 people are attempting to set 55 Guinness World Records today when running the London Marathon and here is a selection on some of the most peculiar. 

• Ian Bates from Crawley is wearing a 20kg costume, trying to break the record for fastest time dressed as a 3-D dinosaur. 
• Gill Punt from Essex has raised £250,000 for Cancer Research UK, following the death of her father, and is hoping to beat the time of four hours 30 minutes, while dressed as a polar bear, to claim the title for fastest marathon in a full body animal costume (female).
• Firefighters Lee Small, James Lafferty, Michale Palmer and Stevie Clifford-Tucker are celebrating the 150th birthday of the London Fire Brigade by dressing as a fire engine and attempting to beat the time of six hours 30 minutes to earn the title of fastest marathon in a four-person costume.

Some people just love punishment I guess. This gent has loved this experience so much and seemingly feels so fresh, he's banging out press ups in front of Buckingham Palace.

I have just identified this gent as Andrew Lilley.
